I’d like to operate a Business and Trade Organization outside the US. If I have a sole-proprietorship type of business, can I do that? If I decide to form an alliance with another business outside the country, would I have to change into a Corporation?
You can absolutely operate as a Sole Proprietor and still have have alliance with another company.
Whether you have strategic partnership or contractual partnership, you should be able to show revenue on your tax form as a sole proprietor. The taxes are very complicated, depending on which company you are operating in because I know someone who has a similar business model. There are accountants that specialize in this area and you can consult them.
